Cable and antenna analyzer specifications
apply under these conditions:
• Cable and antenna measurements apply
after calibration to OSL standards.
• The instrument is operating within a
valid calibration period.
• Data without tolerance are considered
typical values.
• Typical or nominal values are defined as:
– Typical: Expected instrument per-
formance operating under 20 to 30°C
when remaining at this temperature
for 15 minutes.
– Nominal: A general, descriptive term
or parameter.
All specifications subject to change without
notice.
